Hepatocyte growth factor (HGF) and its receptor c-Met are associated with increased aggressiveness of tumors and poor prognostic outcome of patients with cancer. Here, we report the development and characterization of therapeutic anti-HGF (aHGF)-Nanobodies and their potential for positron emission tomographic (PET) imaging to assess HGF expression in vivo. Two aHGF-Nanobodies designated 1E2 and...

OBJECTIVE The clinical history of bone metastases and skeletal-related events (SREs) secondary to cancers is not well understood. In support of studies of the natural history of bone metastases and SREs in Danish prostate and breast cancer patients, we estimated the sensitivity and specificity of hospital diagnoses for bone metastases and SREs (ie, radiation therapy to the bone, pathological or...

Angiogenesis is a highly regulated process orchestrated by the VEGF system. Heparin/heparan sulfate (HS) proteoglycans and neuropilin-1 (NRP-1) have been identified as co-receptors, yet the mechanisms of action have not been fully defined. In the present study we characterized molecular interactions between receptors and co-receptors, using surface plasmon resonance (SPR) and in vitro binding a...

Background: Colorectal cancer is the third most common type of aggressive cancers. Chemotherapy, surgery,and radiotherapy are the common therapeutic options for treating this cancer. Due to the adverse side-eff ects of these methods, immunotherapy is considered as an appropriate alternative therapeutic option. Treatment through the application of monoclonal antibodies is considered as a n...

RIT has become an attractive strategy in cancer treatment, but still faces important drawbacks due to poor tumor penetration and undesirable pharmacokinetics of the targeting vehicles. Smaller radiolabeled antibody fragments and peptides feature highly specific target accumulation, resulting in low accumulation in healthy tissue, except for the kidneys. Nanobodies are the smallest (MW<15 kDa) f...

Objective(s): Filamentous bacteriophage M13 was genetically engineered to specifically target mammalian cells for gene delivery purpose. Materials and Methods: A vascular endothelial growth factor receptor 2 (VEGFR2)-specific nanobody was genetically fused to the capsid gene III of M13 bacteriophage (pHEN4/3VGR19). A mammalian expression construct containing Cop-green fluorescent protein (Cop-G...

The development of dual-imaging enabled cancer-targeting nanoparticles (DICT-NPs) is reported based on newly developed biodegradable photoluminescent polymers and superparamagnetic iron oxide nanoparticles. DICT-NPs possess capabilities of dual-imaging (magnetic resonance imaging and optical imaging), magnetic targeting, and potentially selective targeting for cancer cells. The development of D...

Abstract Cancer is the second leading cause of death worldwide after cardiovascular disease. Depending on type and location tumor, several cancer treatments are implemented. Among these, three most conventional therapies surgery, radiotherapy chemotherapy. However, there other therapeutic approaches such as photodynamic therapy (PDT). PDT relies combined action light, a photoactivable molecule ...
